They need to implement the defense code from the consoles version.
That version is becoming more fun to play, while the PC/Mobile version is becoming less fun.
I love the AI missing a 5er skull move, or making a 4er instead of a 5er, or just not seeing a 4/5er move at all.
I love how you can set gem color preference for your defense team, and how it can decide to not make skull moves, but cast a spell instead.
It's a lot more unpredictable.
Of course, the 10 4/5er moves falling into the screen, one after another, or even just 3er moves that keep forming 20 in a row, has to be stopped for all versions. Recall bias or not, remove it for player as well for AI, and it's still fair, but you can actually play with strategy, instead of relying on dumb luck.
